Questions about Clockwise Bimax

[emocel]

I have the typical deep bite + short chin + long ramus combo. This has caused some functional issues so I will likely be able to get a bimax. What I want is to get a steeper gonial angle without recessing my chin or changing my midface.
1. Will it lengthen the midface?
2. Will genio be needed alongside it if my chin is relatively short and not projected?

Your depends on the surgeon's manipulation of the occlusal plane (bite plane). In cases of deep bite, rotating the mandible forward and downward both improves function and supports that sharp line you want
Requesting a profile simulation via VSP from your surgeon will allow you to clearly see the balance between the midface and the chin
This analysis is based on general surgical principles however, since your bone density and soft tissue thickness will directly affect the result, it is best to have a cephalometric analysis performed by an oral surgeon

Can I hire you to be next to the surgeon during the operation so you guide him?

If you pay for my plane ticket

aren't ccw (upwards) better for class II? Deep bite + short chin

Same problem but bimax is a big protrudcutre ahit u got it covred go for it jsut its not without risk of swelling numbness recvory time etc.

Again tho it is usally rhe most cases of life altercation so if you can get it corvred but id personally do a bsso with genio assuimg a class 2 at least I got told to do it.

My case I could use braces and a genio but we're diffrent and it really depends how severe ur bite is

True but with a long ramus and deep bite, CW rotation can actually balance vertical proportions and define the gonial angle better

that's counterintuitive to me ngl

do you know the science behind it? Because I have the same problems and my surgeon recommended ccw even with me saying I consider the looks the most important

I have this image for reference, but now I am asking myself if I got these rotations right, 'cause for my understanding the only thing that makes sense is ccw for a recessed lower jaw

You actually have the labels swapped CCW brings the chin up/forward. Surgeons love CCW for airway health, but with a long ramus, it can flatten the jaw angle too much. CW is sometimes used specifically to drop that angle and keep the jawline looking steep and sharp
